SPECIFICATION forming part of Letters Patent No. 368,646, dated August 23, 1887.

Application filed May 23, 1887.

To @ZZ whom it may concern:

Be it known that l, GEORGE W. BROWN, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sash-Locks; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine. l

My invention relates to the construction of locks or fasteners for the meeti 11g-rails of sashes, and has for its object to simplify and cheapen the construction and at the same time to greatly improve the mode of operation in use.

Numerous devices of this general class have heretofore been produced; but none of them have completely met the requirements of the trade. It is necessary in devices of this class that they should be strong, of few parts, easy to operate, and so constructed as not to bruise the parting strip 0r head of the jamb. Itis furthermore desirable that they should hold the two sashes balanced-that is, avoid all lateral pull upon either sash, draw the two meeting-rails toward each other,that as little ofthe fastener as possible should be in sight, while at the same time but little wood-work be re moved to weaken the rail, and lastly that the parts shall not assume the locked position until both sashes are fully closed. In order to accomplish these results, I have devised the simple and novel construction of which the followingr description, in connection with the accompanyingdrawings,is'aspecication,num

y bers being used to indicate the several parts.

Figure 1 is a transverse section of the two meeting-rails of a window and of my improved fastener, the parts being in the unlocked position; Fig. 2, a similar view, the parts beingin the locked position; Fig. 3, a plan view of the keeper upon the lower sash 5 Fig. 4, a plan View of the housing and catch upon the upper sash, and Figs. 5 and 6 are perspectives of the two parts of the fastener, the meeting-rails being shown in dotted lines.

It will be observed thatl the entire device consists of four parts only in addition to the attaching-screws.

Serial No. 239,043. (No model.)

1 denotes the upper rail of the lower sash, and 2-thelower rail ofthe upper sash.

3 denotes the housing; 4L, the catch pivoted therein; and 5,a spring, the action of which is .to throw the catch to its locked position. The

housing is let into a recess cut in the front of rail 2. The housing is provided with an attachingplate, 6, which may be recessed into the top of rail 2 or may rest upon it, as shown in the drawings. Two screws extending straight down into the rail will be found quite sufficient to hold it iirmly in place. On opposite sides of the housing are plates or blocks of metal 7, which are let into the front of rail 2, a single square mortise in the rail serving to receive both the plates or blocks and the housi-ng. These plates or blocks in use come in contact with similar plates or blocks upon the upper rail, 1, of the lower sash. The catch projects upward through an opening, 8, in the top of the housing and is provided with the usualengaging-shoulder,9,androundedface10.

It will be noticed in Fig. 1 that the top of the housing is lower than the surface ofthe attaching-plate,leaving a shoulder, 11, which is engaged by the keeper, as will presently be more fully explained.

12 denotes the keeper, which is provided with an attaching-plate, 13, which is either recessed into the top of rail 1 or rests upon it, as shown in the drawings, screws being used to hold it in place in the same manner that the housing is secured. The top ofthe keeper is provided with an opening, 14, to receive the catch,and the face thereof is provided with a recess, 15, to receive the housing when the sashes are in the locked position. On opposite sides of this recess are plates or blocks of metal 16, which are let into the back of rail 1, asingle square mortise in the back ofthe rail serving to receive the entire face of thekeeper. When the sashes are thrown to the closed position the rounded face of the catch passes up through opening 14, forcingthe catch back, the housing at the same time passing into recess l5. When the sashes reach the closed position, plates or blocks 7 upon the lower rail of the upper sash will rest closely against plates or blocks 16 upon the upper rail of the lower sash, the housing will be wholly within re- ICO cess 15, and the face of the keeper will rest upon the top of the housing, lying closely against shoulder 11, asis clearly shown in Fig. 2. The instant that the keeper comes in contact with shoulder 11 the surfaces of attaching-plates 6 and 1,3 will be in the same horizontal plane and the catch will spring over the front ofthe keeper, thus locking the sashes rmly together.

It will be seen that the engagement 'of the housing with recess 15 necessarily centers the two sashes and that the action of the catch is to draw the two sashes rmly together. It will furthermore be seen that it is impossible for the catch to be thrown to its locked position until both sashes are fully closed, thus obviating a serious objection to many fasteners of this kind in which it is quite common to throw the catch or bolt to the locked position without any engagement being made between the sashes. To disengage the sashes from each other it is simply necessary to pull the catch forward, it being easily reached for that purpose. This leaves the sashes wholly disengaged,so that the upper one maybe lowered or the lower one raised, or both.

It will be seen that my improved fastener is simple, strong, easy to operate, and that it cannot possibly be operated from the Outside without breaking the glass, and that it is impossible for the slightest damage to be done to the wood-Work in use.

Having thus described my invention, I claim- A housing, an attaching plate having a shoulder, 11, and a springcatch pivoted in said housing and having a rounded face and engaging-shoulder projecting above the housing,in combination with a keeper having a recess to receive the housing, and an opening through which the catch passes and which is adapted to rest on shoulder ll when the parts are in the locked position.

In testimony whereof I affix my signaturein presence of two Witnesses.
